Question

what is limiting friction what are the laws of limiting friction

Answer 1

the maximum frictional force surface can exert is call limiting frictional force ..

laws :
the body needs to overcome limiting frictional force to come in motion
if the force applied is less than the limiting friction then the surface exerts same amount of force and resists body to move

Answer 2

Laws of limiting friction:

(i) The force of limiting friction depends upon the nature of surfaces in contact and-acts tangentially to the interface between the two surfaces.

(iii) Limiting friction is directly proportional to the magnitude of normal reaction N between two surfaces in contact, i.e.
